The average Earth-Moon distance is 3.84 X 10^5 km, while the Earth-Sun is 1.496 X 10^8 km. Since the radius of the Moon is
1.74 X 10^3 km and that of the Sun is 6.96 X 10^5 km.
a) Calculate the angular radius of the Moon and the Sun, qmax, according to the following figure.

b) Calculate the solid angle of the Moon and the Sun as seen from Earth.
(c) Interpret its results; Would this be enough to explain the occurrence of total solar eclipses?
Thank you for the explanation, but this didn't answer my question. I need to know the angles for qeustion 2, 3, and 4. With explanations on how to get them.
Suppose, we recently discovered a new planet named Concordia. If for 15 degrees
difference, the distance between Cansae City and and Cantabrigia City would have
been 6050 stadia. According to Erasthosthenes' calculation, what would have been
the circumference of Concordia?
5.45E5 stadia
2.45E5 stadia
4.45E5 stadia
1.45E5 stadia
3.45E5 stadia

- Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion. Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU. Does this make physical sense? Explain why or why not.arrow_forwardIn Ptolemys model, which of the followingepicycle, equant, or deferenttravels in uniform circular motion as viewed from a particular point?

- Why did Plato propose that all heavenly motion was uniform and circular?arrow_forwardThe geocentric model, in all of its complexity, survived scientific scrutiny for almost 1,400 years. However, in modern astronomy, scientists seek to explain the natural and physical world we live in as simply as possible. The complexity of Ptolemy's model was an indicator that his theory was inherently flawed. Why, then, was the geocentric model the leading theory for such a long time, even though the heliocentric model more simply explained the observed motions and brightness of the planets? Check all that apply. ☐ The geocentric model conformed to both the philosophical and religious doctrines of the time. ☐ The heliocentric model did not make noticeably better predictions than the geocentric model. From Earth, all heavenly bodies appeared to circle around a stationary Earth. The complexity of the geocentric model was appealing to most ancient astronomers. Ancient astronomers did not observe stellar parallax, which would have provided evidence in favor of the heliocentric model.arrow_forwardNeptune orbits the Sun with an orbital radius of 4.495 x 10^12 m.

Aplanet such as Mars moves slowly from west to east against the fixed background stars and then mysteriously reverses direction for a period of time before resuming its previous path (Fig. 1.2). Attempting to understand this backward, or retrograde, motion became the principal problem in astron- omy for nearly 2000 years! Eudoxus of Cnidus, a student of Plato's and an exceptional mathematician, suggested that each of the wandering stars occupied its own sphere and that all the spheres were connected through axes oriented at different angles and rotating at var- ious speeds. Although this theory of a complex system of spheres initially was marginally successful at explaining retrograde motion, predictions began to deviate significantly from the observations as more data were obtained.arrow_forwardWhat makes Ptolemaic model different from Copernican model of the universe? Explain your answer.arrow_forward
- O Jupiter's third-largest natural satellite, lo, follows an orbit with a semimajor axis of 422,000 km (4.22 × 105 km) and a period of 1.77 Earth days (Plo = 1.77 d). To use Kepler's Third Law, we first must convert lo's orbital semimajor axis to astronomical units. One AU equals 150 million km (1 AU = 1.50 x 108 km). Convert lo's a value to AU and record the result. alo = AUarrow_forward(a) Graph the point in a polar coordinate system. (5, 1) 2 -2 -2 Convert the given polar coordinates to rectangular coordinates.
